The Odessa 9 features a 1.1″ tube, allowing you to fully utilize your stock sights. That’s right, the Odessa 9 is almost as small as the Mask. It is also fully modular and can be shot in multiple configurations. 9 to be exact (well, 10 if you don’t use ANY baffles). If you stack only four baffles you’ll be close to, or below, hearing safe levels with subsonic ammunition. Stack on the full 10 baffles and they’ve hovered just shy of 122dB with HUSH subsonic ammo.
